I just realized how tough this fight could possibly be. Ortiz is a big ass southpaw and Floyd has had his most trouble with guys practically 2 weight classes above him on fight night (Castillo, Oscar). I hope Floyd can get Ortiz's respect or this fight coulf get dangerous

This is true, but it certainly helps to be bigger and maybe strnger than your opponent. Floyd doesn't seem too worried. He actually said come fight night he is going to "look" bigger because he is at the weight already and can build from there and eat, whereas Ortiz has to lose alot to get down to 47.
